Some (many?) Stack Exchange sites have Twitter accounts: Stack Overflow has @StackOverflow, Japanese StackOverflow has @jaStackOverflow, English Language Learners has @StackEnglishLL, Chinese Stack Exchange has @StackChinese, Russan SE has @StackRussian, Chess SE has @StackChess, etc.
Retweeting tweets from such accounts can help in promoting the site.
So, does Language Learning SE have a Twitter account? If yes, where is it? I have not been able to find it.
- Beta sites do not automatically get a Twitter account. See Why is it so difficult to find the twitter account for a Stack Exchange site? on Meta SE.
- Jeff Atwood's blogpost Twitter Question Feeds for Stack Exchange from January 2011 has a list of Twitter accounts that were available at that point in time.
